Hamlet, Prince of Sarcasm:

LORD POLONIUS What do you read, my lord?HAMLET Words, words, words.LORD POLONIUS What is the matter, my lord?HAMLET Between who?LORD POLONIUS I mean, the matter that you read, my lord.HAMLET Slanders, sir: for the satirical rogue says here that old men have grey beards, that their faces are wrinkled, their eyes purging thick amber and plum-tree gum and that they have a plentiful lack of wit, together with most weak hams: all which, sir, though I most powerfully and potently believe, yet I hold it not honesty to have it thus set down, for yourself, sir, should be old as I am, if like a crab you could go backward.
